Nanoflower for CO2 capture by Qilei Song and Wen Liu

This image shows the microstructure of layered double hydroxides (LDHs) material taken by scanning electron  microscope. The flower-like microstructure provides a large  surface-area-to-volume-ratio, which is beneficial for catalysis,  chemical reactions, and CO2 capture applications. The thin LDHs  crystals (10-20 nm) consist of multiple layers of homogeneous  dispersed cations, and anions between the layers (as shown in the  inset). With rational design of material chemistry, we synthesised  highly-reactive and thermally-stable metal oxides from LDHs and  demonstrated their applications in energy and environmental processes,  such as chemical looping for CO2 capture and H2 production, CO2  capture sorbents, catalytic removal of exhausts of diesel engines, and  catalysts for sustainable synthetic fuels. The LDHs could also serve  as nanoreservoir and carriers for molecules and ions after proper  modification, for applications in drug delivery, CO2 storage,  lithium-ion battery for energy storage, and ion removal from  contaminated water, some of which are closely related to research  activities of several groups in the department. From this image, we  show that by understanding the fundamental chemical science and  engineering design of novel technology, we can provide innovative  solutions to global challenges in energy, environmental,  sustainability and healthcare.
